CPU speed setting for Amiberry in Retropie

S. Campbell · 04 October 2021, 15:26

I finally managed to get Tronic Kids running at a decent speed on Amiberry on my Raspberry Pi 4 by changing the CPU speed in the settings from 14MHz to "Fastest".

However, I have no idea what I should be putting in the .UAE config file to achieve that end without having to manually change it every time I play. All I have in there relating to the CPU is:

; *** CPU options
;
finegrain_cpu_speed=1024
cpu_type=68030
cpu_model=68030
cpu_compatible=false
cpu_24bit_addressing=false
fpu_no_unimplemented=true
fpu_strict=false
compfpu=true
cachesize=0

Anyone know what should go in there?

Never mind: by a convoluted method I figured out it was cpu_speed=max.

WOULD IT KILL PEOPLE TO USE THE SAME LANGUAGE IN THE CONFIG FILE AS THEY DO ONSCREEN?

The config file predates any of the (many) GUIs that use UAE as the emulation core. It might make sense for the GUI to use the config file terminology, but then again, a GUI is supposed to be easy for an end user to understand, so it's pretty normal for the language to be modified from the terse .rc syntax used by terminal junkies.

A quick glance at the UAE documentation, or the documentation of any of the common derivatives shows all the configurations options available. For example, and the FS-UAE documentation includes a nice list and good descriptions (legacy UAE options like cpu_speed are prepended with uae_).

Edit: Just realised that this is in Support.WinUAE. Support.OtherUAE might be more appropriate.
